I have a 2004 vw golf i'm looking to install a carputer w/ a 7-10.4" touchscreen

and i want to either relocate the temp controls knobs or modify them so I can control them with the carputer, if anyone as any idea i'm open to sugestions.

is there any hardware and software i could purchase to make this happen? i found something to control my windows, sunroof, gas latch ect. but i want to control climate w/carputer also.
